Popup

Popups

To create a popup, add the data-role="popup" attribute to a div with the popup contents. Then create a link with the href set to the id of the popup div, and add the attribute data-rel="popup" to tell the framework to open the popup when the link is tapped. This is a similar markup pattern to the dialog widget. A popup div has to be nested inside the same page as the link.

<a href="#popupBasic" data-rel="popup">Open Popup</a>
 
<div data-role="popup" id="popupBasic">
  <p>This is a completely basic popup, no options set.</p>
</div>

This will result in the following popup:

The popup consists of two elements: the screen, which is a transparent or translucent element that covers the entire document, and the container, which is the popup itself. If your original element had an id attribute, the screen and the container will each receive an id attribute based on it. The screen's id will be suffixed with "-screen", and the container's id will be suffixed with "-popup" (in the above example, id="popupBasic-screen" and id="popupBasic-popup", respectively).

The framework adds a small amount of margin to text elements, but it's really just a container with rounded corners and a shadow which serves as a blank slate for your designs (even these features can be disabled via options). Please note that if you want to add a header to the popup and also have a closing button, the markup for the header must come first.

This simple styling makes it easy to add in widgets to create a variety of different interactions. Here are a few real-world examples that combine the various settings and styles you can achieve out of the box with popups:

Scaling images: Lightbox examples

The framework CSS contains rules that make images that are immediate children of the popup scale to fit the screen. Because of the absolute positioning of the popup container and screen, the height is not adjusted to screen height on all browsers. You can prevent vertical scrolling with a simple script that sets the max-height of the image.

In the two examples below the divs with data-role="popup" have a class of photopopup.

The handler is bound to the popupbeforeposition event, which ensures the image is not only scaled before it is shown but also when the window is resized (e.g. orientation change). In this code example the height is reduced by 60 to take a top and bottom tolerance of 30 pixels into account.

$( document ).on( "pagecreate", function() {
    $( ".photopopup" ).on({
        popupbeforeposition: function() {
            var maxHeight = $( window ).height() - 60 + "px";
            $( ".photopopup img" ).css( "max-height", maxHeight );
        }
    });
});

Working with iframes in popups

You may need to embed an iframe into a popup to use a 3rd party widget. Here, we'll walk through a few real-world examples of working with iframes: videos and maps.

Video example

Here is an example of a 3rd party video player embedded in a popup:

The markup is an iframe inside a popup container. The popup will have a 15 pixels padding because of class ui-content and a one pixel border because the framework will add class ui-body-a to the popup.

<div data-role="popup" id="popupVideo" data-overlay-theme="b" data-theme="a" data-tolerance="15,15" class="ui-content">
 
    <iframe src="http://player.vimeo.com/video/41135183" width="497" height="298" seamless></iframe>
 
</div>

When using an iframe inside a popup it is important to initially set the width and height attributes to 0. This prevents the page to breaking on platforms like Android 2.3. Note that you have to set the attributes, because setting the width and height with CSS is not sufficient. You can leave the actual width and height in the markup for browsers that have JavaScript disabled and use attr() to set the zero values upon the pageinit event.

Next, bind to the popupbeforeposition event to set the desired size of the iframe when the popup is shown or when the window is resized (e.g. orientation change). For the iframe examples on this page a custom function scale() is used to scale down the iframe to fit smaller screens. Expand the section below to view the code of this function.

function scale( width, height, padding, border ) {
    var scrWidth = $( window ).width() - 30,
        scrHeight = $( window ).height() - 30,
        ifrPadding = 2 * padding,
        ifrBorder = 2 * border,
        ifrWidth = width + ifrPadding + ifrBorder,
        ifrHeight = height + ifrPadding + ifrBorder,
        h, w;
 
    if ( ifrWidth < scrWidth && ifrHeight < scrHeight ) {
        w = ifrWidth;
        h = ifrHeight;
    } else if ( ( ifrWidth / scrWidth ) > ( ifrHeight / scrHeight ) ) {
        w = scrWidth;
        h = ( scrWidth / ifrWidth ) * ifrHeight;
    } else {
        h = scrHeight;
        w = ( scrHeight / ifrHeight ) * ifrWidth;
    }
 
    return {
        'width': w - ( ifrPadding + ifrBorder ),
        'height': h - ( ifrPadding + ifrBorder )
    };
};

When the popup is closed the width and height should be set back to 0. You can do this by binding to the popupafterclose event.

This is the complete script and the link to open the video popup:

$( document ).on( "pageinit", function() {
    $( "#popupVideo iframe" )
        .attr( "width", 0 )
        .attr( "height", 0 );
 
    $( "#popupVideo" ).on({
        popupbeforeposition: function() {
            var size = scale( 497, 298, 15, 1 ),
                w = size.width,
                h = size.height;
 
            $( "#popupVideo iframe" )
                .attr( "width", w )
                .attr( "height", h );
        },
        popupafterclose: function() {
            $( "#popupVideo iframe" )
                .attr( "width", 0 )
                .attr( "height", 0 );
        }
    });
});

Note that the video will still be playing in the iframe when the popup is closed. If available you can use the 3rd party API to stop the video on the popupafterclose event. Another way is to create the iframe when the popup is opened and destroy it when the popup is closed, but this would drop support for browsers that have JavaScript disabled.

Map example

In the second example, an iframe is used to display Google Maps API. Using an iframe prevents issues with the controls of the map.

This is the markup of the popup including a right close button:

<div data-role="popup" id="popupMap" data-overlay-theme="b" data-theme="b" data-corners="false" data-tolerance="15,15">
 
    <a href="#" data-rel="back" data-role="button" data-theme="b" data-icon="delete" data-iconpos="notext" class="ui-btn-right">Close</a>
 
    <iframe src="map.html" width="480" height="320" seamless></iframe>
 
</div>

Expand the section below to view the source of the iframe.

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>Map</title>
    <script>
        function initialize() {
            var myLatlng = new google.maps.LatLng( 51.520838, -0.140261 );
            var myOptions = {
                zoom: 15,
                center: myLatlng,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            }
            var map = new google.maps.Map( document.getElementById( "map_canvas" ), myOptions );
        }
    </script>
    <script src="http://maps.google.com/maps/api/js?sensor=false"></script>
    <style>
        html {
            height: 100%;
            overflow: hidden;
        }
        body {
            margin: 0;
            padding: 0;
            height: 100%;
        }
        #map_canvas {
            height: 100%;
        }
    </style>
</head>
<body onload="initialize()">
 
    <div id="map_canvas"></div>
 
</body>
</html>

Setting the size of the iframe is done exactly the same as for the video example, with one exception. You should also set the width and height of the div that contains the map to prevent the page from breaking on platforms like Android 2.3. In this example the ID of this div is #map_canvas.

This is the complete script and the link to open the map popup:

$( document ).on( "pageinit", function() {
    $( "#popupMap iframe" )
        .attr( "width", 0 )
        .attr( "height", 0 );
 
    $( "#popupMap iframe" ).contents().find( "#map_canvas" )
        .css( { "width" : 0, "height" : 0 } );
 
    $( "#popupMap" ).on({
        popupbeforeposition: function() {
            var size = scale( 480, 320, 0, 1 ),
                w = size.width,
                h = size.height;
 
            $( "#popupMap iframe" )
                .attr( "width", w )
                .attr( "height", h );
 
            $( "#popupMap iframe" ).contents().find( "#map_canvas" )
                .css( { "width": w, "height" : h } );
        },
        popupafterclose: function() {
            $( "#popupMap iframe" )
                .attr( "width", 0 )
                .attr( "height", 0 );
 
            $( "#popupMap iframe" ).contents().find( "#map_canvas" )
                .css( { "width": 0, "height" : 0 } );
        }
    });
});

Calling the popup plugin

This plugin will autoinitialize on any page that contains a div with the attribute data-role="popup". However, if needed you can directly call the popup plugin on any selector, just like any jQuery plugin and programmatically work with the popup options, methods, and events API:

$( "#myPopupDiv" ).popup();

Opening popups

Using the markup-based configuration, when a link with the data-rel="popup" is tapped, the corresponding popup container with the id referenced in the href of the link will be shown. To open a popup programmatically, call popup with the open method on the popup container:

$( "#myPopupDiv" ).popup( "open" )

Closing popups

By default popups can be closed either by clicking outside the popup widget or by pressing the Esc key. To prevent this, the data-dismissible="false" attribute can be added to the popup. Popups can also be closed via the close method:

$( "#myPopupDiv" ).popup( "close" )

To add an explicit close button to a popup, add a link with the role of button into the popup container with a data-rel="back" attribute which will close the popup when tapped. We have created helper classes to position buttons in the upper left (ui-btn-left) or upper right (ui-btn-right) of the popup but you may need to tweak these or add custom positioning styles depending on your design. We recommend adding standard content padding to the popup to make room for the buttons (see next section).

<div data-role="popup">
  <a href="#" data-rel="back" data-role="button" data-theme="a" data-icon="delete" data-iconpos="notext" class="ui-btn-right">Close</a>
  ...popup contents go here...
</div>

Adding padding

For popups with formatted text, padding is needed. We recommend adding the ui-content class to the popup container which adds the standard 1em (16px) of padding, just like the page content container. Write your own styles to create a more customized design if needed.

<a href="#popupPadded" data-rel="popup" data-role="button">Popup with padding</a>
 
<div data-role="popup" id="popupPadded" class="ui-content">
  <p>This is a popup with the <code>ui-content</code> class added to the popup container.</p>
</div>

This will result in the following popup with content padding:

When padding is added, we apply a few style rules to negate the top margin for the first heading or paragraph in the popup and do the same for the last element's bottom margin. This keep the popups from having too much vertical space when the content padding and element margins combine.

Positioning options

By default, popups open centered vertically and horizontally over the thing you clicked (the origin) which is good for popups used as tooltips or menus. The framework also applies some basic collision detection rules to ensure that the popup will appear on-screen so the ultimate position may not always be centered over the origin.

For situations like a dialog or lightbox where the popup should appear centered within the window instead of over the origin, add the data-position-to attribute to the link and specify a value of window.

It's also possible to specify any valid selector as the value of position-to in addition to origin and window. For example, if you add data-position-to="#myElement" the popup will be positioned over the element with the id myElement.

A few examples:

The popup's placement constraints, which may cause the popup not to appear centered as desired, are as follow:

1. The width of the popup will be limited using CSS max-width to the width of the window minus a tolerance of 15px on either side.
2. A tolerance from the edges of the window (15px from each of the sides and 30px from the top and the bottom) will be observed when the popup fits inside the window. Tall popups are allowed to overflow the top and bottom edges of the window. Those parts of the popup can be viewed by manually scrolling the document. This tolerance can be configured via the tolerance option.
3. The top coordinate of the popup will never be negative. This ensures that the top of the popup will not be cut off.
4. If centering the popup over an element would cause the overall height of the document to increase, the popup is shifted upwards at most until its top coordinate becomes 0.

Also note that a popup is currently always placed at the center of the window after an orientation change or window resize event.

See methods for information about setting the popup position programmatically, including the option to specify x and y coordinates.

Setting transitions

By default, popups have no transition to make them open as quickly as possible. To set the transition used for a popup, add the data-transition attribute to the link that references the popup. The reverse version of the transition will be used when closing the popup.

<a href="#transitionExample" data-transition="flip" data-rel="popup">
   Flip transition
</a>

For performance reasons on mobile devices, we recommend using simpler transitions like pop, fade or none for smooth and fast popup animations, especially with larger or complex widgets within a popup. To view all transition types, you must be on a browser that supports 3D transforms. By default, devices that lack 3D support (such as Android 2.x) will fallback to "fade" for all transition types. See the transitions page for detailed information on the transition system.

When you launch the popup from any of the buttons, the data-transition set on the button will be used. However, if you launch the popup programmatically, such as via $( "#transitionExample" ).popup( "open" ), the data-transition attribute specified in the definition of the popup will be used if present.

Theming the popup and overlay

The popup plugin provides two theme-related options: data-theme and data-overlay-theme. The data-theme option refers to the theme of the popup itself, whereas data-overlay-theme refers to the theme of the popup's background, which covers the entire window behind the popup.

data-theme will be inherited from the page, and will always have a valid value when the popup opens, unless you explicitly specify data-theme="none", in which case the popup will have a transparent background.

The data-overlay-theme will never be set, and the popup's background, although always present when the popup is shown, will be completely transparent, unless explicitly set using for example data-overlay-theme="b". In this case, the background will fade in, partially obscuring the rest of the window, to further direct attention to the popup. Here is an example of an explicitly themed popup:

<div id="both" data-role="popup" data-theme="b" data-overlay-theme="a" class="ui-content">
  ...Popup contents...
</div>

Arrows

The extension widgets/popup.arrow provides the arrow option, which is also exposed as a data attribute. For example, data-arrow="t,b" will result in the popup being displayed with a top or a bottom arrow.

When an arrow is requested using the arrow option, the popup is positioned along one of the edges of the popup such that the arrow points at the center of the origin. The value of the arrow option is a comma-separated list of letters referring to the edges of the popup along which the framework should attempt to place the arrow:

For each edge given in the list, the framework calculates

1. the distance between the tip of the arrow and the center of the origin, and
2. whether minimizing the above distance would cause the arrow to appear too close to one of the corners of the popup along the given edge.

Thus, the order in which the edges are given matters.

The example below shows a popup with an arrow either along its left edge or along its top edge.

<div data-role="popup" data-arrow="l,t" class="ui-content">
  <h2>Popup with an arrow</h2>
  <p>A second paragraph.</p>
</div>

Note: Chaining of popups not allowed

This also means that custom select menus will not work inside popups, because they are themselves implemented using popups. If you place a select menu inside a popup, it will be rendered as a native select menu, even if you specify data-native-menu="false".

A workaround to get chained popups working is the use of a timeout for example in the popupafterclose event bound to the invoking popup. In the following example, when the first popup is closed, the second will be opened by a delayed call to the open method:

$( document ).on( "pageinit", function() {
    $( ".popupParent" ).on({
        popupafterclose: function() {
            setTimeout(function() { $( ".popupChild" ).popup( "open" ) }, 100 );
        }
    });
});

Providing pre-rendered markup

You can improve the load time of your page by providing the markup that the popup widget would normally create during its initialization.

By providing this markup yourself, and by indicating that you have done so by setting the attribute data-enhanced="true", you instruct the popup widget to skip these DOM manipulations during instantiation and to assume that the required DOM structure is already present.

When you provide such pre-rendered markup you must also set all the classes that the framework would normally set, and you must also set all data attributes whose values differ from the default to indicate that the pre-rendered markup reflects the non-default value of the corresponding widget option.

The popup widget moves the element on which it is instantiated such that it becomes the last child element of a page div or, if the element is not inside a page, it will become the last child element of the body. It then wraps the element in a container div, and prepends a newly created element that serves as the modal overlay screen to the parent of the container.

The example below includes an entire jQuery Mobile page rather than just the popup. This helps illustrate where you must place the markup for the pre-rendered popup widget in relation to the jQuery Mobile page on which it is to appears. In the example, the popup has the attribute data-overlay-theme="b" to reflect the fact that the modal overlay screen has an associated theme.

<div data-role="page">
  <div data-role="header">
    <h1>Example Page</h1>
  </div>
  <div role="main" class="ui-content">
    <a href="#pre-rendered" data-rel="popup" class="ui-btn ui-corner-all ui-shadow ui-btn-inline">Open pre-rendered popup</a>
  </div>
  <!-- the following two divs represent the pre-rendered popup widget -->
  <div class="ui-popup-screen ui-overlay-b ui-screen-hidden"></div>
  <div class="ui-popup-container ui-popup-hidden ui-popup-truncate" id="pre-rendered-popup">
    <div class="ui-popup ui-body-inherit ui-overlay-shadow ui-corner-all" id="pre-rendered" data-role="popup" data-enhanced="true" data-overlay-theme="b">
      <p>Pre-rendered popup</p>
    </div>
  </div>
</div>

Multiple types supported:
